In the Super Mario Bros. Power Up Card Game, you want to survive the perils of the Mushroom Kingdom and make it safely to the Castle, but to do that, you'll need to use your wits and deduction skills to figure out how to take out everyone else who might beat you there.

Each round, players receive a secret level card at random, with these cards being numbered 1-12. After looking at their card, each player in order can swap their card with the one held by their right-hand neighbor. Will you get something better? Maybe! If someone has a castle card, they're immune from trade or disasters this round. After everyone has traded or passed, players can play "? Block" power-ups to affect their strength or others. Whoever has the lowest score in a round loses one of their life tokens, and if you lose all four life, you're out of the game!
